+x+xDid you use a polishing machine?
Typically I find using a buffer machine is the only way to go, you have not said said how you did this.
I done it via hand, but changed to a diffrent cutting polish and seems to have done much better now
will be hard to get to a high gloss by hand. As well you are using the cutting compound, but after cutting you'll still need a much finer polishing compound to remove the swirls of the cutting compound after using it.
